In September 2017, Mexico experienced an earthquake that knocked down dozens of buildings and killed hundreds of people.
On the morning of September 19, 2017, in Mexico City, an earthquake simulation was held in commemoration of the 1985 earthquake; as it has happened every year since then. Thousands of people left their jobs and schools (and some of their homes) to review emergency measures in the event of an earthquake. Nobody imagined at that moment that a few moments after a real earthquake, they would be put to the test of what was practiced at that time.
That day saw it all. Some, very little; They did not feel it so strongly, or they count. Many others saw their lives pass before their eyes and at one point they thought they were going to die. Others have seen buildings with people inside falling apart. Even many were trapped in the rubble and were saved alive hours or days later. The question is, how does this return to normal after that? And the answer is: she does not come back.
That's why; Humberto Nicolini Sánchez, of the National Institute of Genomic Medicine (Inmegen) began a project that aims to discover how this fact changed the DNA of Mexicans.
Post-traumatic stress after the earthquake could change the DNA of those who have lived [19659007] Nicolini Sánchez and his team began to analyze and compare people suffering from post-traumatic stress with those who were not affected. This in order to discover if there are differences in the epigenome.
According to the presentation of the project before Conacyt the severity of the event lived is correlated with the frequency of post-traumatic stress; and in fact that makes a lot of sense.
Let's start by clarifying what is post-traumatic stress. It is, in short, an anxiety disorder that can occur in people who have experienced trauma endangering their lives or those of their loved ones. The symptoms can last for years and affect your daily life ;
